No they are not the same. Here's a brief description of each:

1. Sony Service Center - a place where you send your Sony products to be serviced and/or repaired. Does not sell retail products.

2. Sony Center - a Sony reseller or retail outlet selling Sony products. Owned by third party and gets their stock through Sony's distributors.

3. Sony Style - Sony's direct retail outlet. Owned by Sony itself. This is why you cannot get street price from Sony Style. They only sell using RRP.

You may find that some Sony Style outlets have a Sony Service Center counter e.g. in KLCC's Sony Style.

Hope that clears the air for you.

Sony Pro Shop currently everyone knows that it's Uncle Chin's shop lar... so no confusion there. Haha.
